Drag the tiles to the correct boxes to complete the pairs. Match the functions to their ranges when the domain is {1, 2}.
f(x) = 3x + 5
f(x) = x2 – 2x – 5
f(x) = (x + 5)x2
f(x) = 4 – x

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?
